COMPOSITION FOR No Drawing.

To all whom it may concern:

3e it known that I, linwxnn H. ELLIS, of 1 \l'inthrop, in the county of Sutlolk and? State of Massachusetts. have invented certain new and useful Improvements in Conipositions for Treating Fuel, of which the following is a specification.

This invention relates to compositions for application to coal and other fuels for the purposes of promoting combustion, reducing to the minimum the escape of unconsnmed carbon and other combustible matter, and the volume of'dense, dark smoke resulting therefrom, and also reducing to the minimum the quantity of ashes and slag or clinkers.

The invention consists in a. composition, the chief ingredients of which are phosphoric acid and black oxid of manganese (inanganese-dioxid). \l'ith these ingredients, 1 preferably employ saltpeter, oxalic acid, and sodium chlorid, the whole being reduced to a. solution orsuspension by the addition of a suitable quant-ityof water, so that the composition may be conveniently applied by sprinkling it upon the coal or other fuel either before or after (preferably before) it is introduced into a furnace or firebox.

Phosphoric acid is a very important ingredient of the composition, andcauses the rapid and copious generation of oxygen when subjected to heat, in the presence of manganese dioxid and particularly in the presonce of the other ingredients specified. For this reason, a, composition containing phosphoric acid may be effectively used in the presence of a much larger proportion of *ater relatively to the chemicals employed than would be possible without the phosphoric-acid; consequently, the economy of the liquid as prepared for use is considerably greator than it. would be without the phosphoric acid.

The black oxid of manganese gives ott oxygen at av relatively low temperature, the evolution of the oxygen being;- facilitated to a marked extent by the employment therewith of phosphoric acid.

' Saltpeter is rich in oxygen and when thrown on burning coal, is an effective ingrcdient. of the composition. ()xalio acid has a tendency to coke soft coal, and thu make a hard mass which will not be consumed as rapidly as the coal in its natural l Specification of Letters Patent.

state. When the coal is quickly coked, the

carbon does not have an opportunity to escape before it is entirely consumed. Sodi ehlorid. when thrown on burning coal, gives a white smoke which neutralizes black smoke from the coal.

The following are the preferred relative proportions of the ingredients specified: phosphoric acid (which is a liquid) 1 pound, black oxid of manganese 1 pound, sal'tpcter 2 pounds, oxalic acid '3 pounds, sodium ehlorid 15 pounds, water 100 gallons. The

said ingredients being thoroughly dissolved or suspended, the solutionis used by sprirr kling it on the fuel, preferably before the latter is introduced into the furnace. The solution should be sprinkled on the fuel. so as to wet. all parts of it. and better results are obtained by putting the fuel in the fire while wet. although, if desired, the solution may be allowed to dry on the fuel before the latter is used.

Practical tests have demonstrated that bituminous coal treated with the described composition. burns without emitting black smoke. the combustion being, more complete; that the quantity of heat given out is increased; that a material saying; of fuel is etlected; and that the quantity of ashes and slag or clinkers produced is materially roduccd. The reason for the decrease in ashes and clinkers is due'to the fact of the perfect combustion which consumes everything coinl u: tible before the tire will go out. of the said comuosition also enables blowers and forced draft apparatuses to be dispensed with; reduces the space required for coal. reduces the quantity of sootdeposited on ilue surfaces. etc. and ,L'lYOHdltiltl' results from relatively low grades of coal than from more expensive coal used without it. The composition may be zulvantagreously app ed to anthracite coal, and other fuels, in wood, peat, etc. It may also be geously used by applying it to a body 0 brick or other refractory material, and ing the latter in or upon a mass of burning coal. The combustion of the fuel in 1th vicinity of said body is found to be comp te and attended with all the above mentioned advantages. The amount of ch mical used to sprinkle fin-l varied, according to uantitv and kind, but a. fair average is two gallons to the cut. finiitlier advantage of this chemical is, that it may be thrown in on top of the fire in the liquid state, causing all of the aforesaid effects.

It will be understood from the foregoing that while I prefer to employ all the ingredients above specified, I may omit some of them and particularly the sodium chlorid.

I claim:

1. A fuel-treating composition, comprising phosphoric acid and black oxid of manganese. r

2. A fuel-treating composition, comprising phosphoric acid, black oxid of manganese, and oxalic acid.

3. A fuel-treating composition, comprising phosphoric acid, black oxid of manganese, and saltpeter.

4:. A fuel-treating composition, comprising phosphoric acid, black oxid of main ganese, oxalic acid, and saltpeter.

5. A fuel-treating composition, comprising phosphoric acid, black oxid of manganese, oxalic acid, saltpeter, and sodium chlorid.

In testimony whereof I have affixed my signature, in presence of two witnesses.
